Problems solved by technology
At present, deflected flow energy dissipation, bottom flow energy dissipation, and surface flow energy dissipation are mainly used. The water velocity at the outlet of the drainage structure is high and the kinetic energy is large, which will cause serious erosion deformation to the downstream riverbed and bank slope, and endanger the downstream buildings. material security
When the high-speed and strong turbulent water flows through the stilling basin, it is easy to cause serious erosion damage to the bottom plate of the stilling basin

The invention discloses an energy dissipating device and an energy dissipating method for a drainage structure, and relates to the vicinity of water conservancy projects. The structure of its energy dissipation part includes steel bars with rings, ropes and stilling pools. The steel bars with rings are respectively inserted into the concrete of the dam site and the back end of the stilling basin according to the specific arrangement position and quantity of the ropes, and the steel bar rings are exposed. Ropes are arranged layer by layer above the stilling pool. When the high-speed discharge water passes through the ridge, the rope arranged downstream of the dam receives the water flow, and the water flow impacting on the surface of the rope reduces the kinetic energy after passing through each layer of rope, which has a buffering effect on the impact force of the water flow and reduces the leakage of the drainage structure. When the water is discharged, the water will scour the downstream riverbed, bank slope and buildings, improve the water conservancy conditions, ensure the energy dissipation efficiency and the safety of downstream buildings, reduce the engineering quantity of building energy dissipation workers, and reduce the project cost.
Description
technical field [0001] The invention relates to an energy dissipating device and an energy dissipating method for a drainage structure, which belongs to the technical field of water conservancy engineering. Background technique [0002] In recent decades, domestic water conservancy and hydropower construction has developed rapidly, and downstream energy dissipation and anti-scour buildings are one of the important parts that affect the safe operation of hydropower projects. At present, deflected flow energy dissipation, bottom flow energy dissipation, and surface flow energy dissipation are mainly used. The water velocity at the outlet of the drainage structure is high and the kinetic energy is large, which will cause serious erosion deformation to the downstream riverbed and bank slope, and endanger the downstream buildings. material security. When the high-speed and strong turbulent water flows through the stilling basin, it is easy to cause serious erosion damage to the ...
